Safety of intracoronary ultrasound: Data from a multicenter European registry

The clinical use of intracoronary ultrasound imaging is growing, serving as a useful adjuvant to contrast angiography, and providing additional information to assist with catheter-based interventions. Despite the increasing use of this technique, it remains an invasive procedure, the safety of which has not been definitively established. Data from multiple European centers performing intracoronary ultrasound (ICUS) examinations were collected under the auspices of the Subgroup on Intravascular Ultrasound of the Working Group on Echocardiography of the European Society of Cardiology. Information was obtained about the number of examinations performed, complications related to ICUS imaging, and any adverse clinical consequences related to ICUS imaging. Twelve centers submitted information about their experience with ICUS. Eight (1.1%) complications were reported (spasm, vessel dissection, or guide wire entrapment) in a total of 718 examinations. All complications occurred in patients with atherosclerotic coronary disease with a diagnosis of unstable or stable angina who underwent percutaneous transluminal coronary angioplasty. No permanent adverse clinical consequences due to ICUS imaging were reported. There was no difference in frequency of complications between centers, as assessed by chi-square analysis (P = 0.232). These data suggest that ICUS examinations can be performed safely with a very low rate of complications. © 1996 Wiley-Liss, Inc.     

改良小梁切除术治疗伴有高眼压及大瞳孔的急性房角关闭

目的 评价改良小梁切除术治疗伴有高眼压及大瞳孔的急性房角关闭的临床疗效。方法收集2005年1月至2009年3月中山大学中山眼科中心青光眼专业实施改良小梁切除术治疗伴有高眼压及大瞳孔的急性房角关闭21例（21眼）的临床资料,对术后并发症及手术前后的眼压、视力、瞳孔等进行统计分析。 结果 术前眼压(48.25±3.14) mmHg,平均用降眼压药种类3.35种,明显高于出院时眼压(10.47±1.15)mmHg(t=11.4573,P＜0.01)及术后3个月眼压(13.86±0.93) mmHg(t=11.2641,P＜0.01)。出院视力(0.09±0.05)与术前视力(0.11±0.06)差异无统计学意义(沁0.8702,P= 0.3913),术后3个月视力(0.21±0.04)则稍好于术前（t=-2.7907,P=0.0112）。术前瞳孔垂直径(5.81±0.23) mm与出院时瞳孔垂直径(5.92±0.21 )mm差异无统计学意义（t=-1.5013,P=0.1672）。无严重并发症发生。 结论 改良小梁切除术是治疗伴有高眼压及大瞳孔的急性房角关闭的有效方法,术中分次放房水、巩膜瓣调节缝线、术毕形成前房等措施可有效减少严重并发症的发生。     

Dental materials: 1979 literature review Part II

This paper, which is presented in two parts, reviews the work on dental materials published in 1979. Included in Part II are sections on impression materials, model, die and investment materials, waxes, acrylic resins, denture base polymers, soft lining materials and tissue conditioners, cast and wrought dental alloys, ceramics, implants and, finally, corrosion. Part I included sections on dental biomechanics, fissure sealants, cements, amalgam, composite filling materials, endodontic materials and microleakage.
